EUGENE GUSY, OF BUFFALO, NEW YORK- WINDOW.

Specification of Letters Patent.

Application filed .Tune 17, 1918. I Serial No. 240,384.

To aZZ whom it may concern:

Be it known that I, EUGENE Gpsr, a citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Windows, of which the following is a specification.

This invention relates more particularly to windows of that class in which the sash is provided with a guide-bar to which the same is pivoted so that it can be reversed forcleaning both sides and which is guided in a runway in the frame for ventilating in the ordinary way. This invention is how- Vation of a window equipped with one form of my improvement. Fig. 2 is an edge view of the sash shown in Fig. 1. Fig. 3 is a horizontal section, on an enlarged scale, taken on line 3-3, Fig. 1. Fig. 4 is a fragmentary sectional elevation of a window showing an embodiment of my invention which differs somewhat in detail from that shown in Figs. 1-3. Fig. 5 is a similar view showing an enlargement of the pivotal connection between the body and guide bar of the sash and adjacent parts. Fig. 6 is a horizontal section taken on the corres 0nd ingly numbered line in Fig. 5. Fig. is a fragmentary sectional perspective view of the weather strip employed in connection with the construction shown in Figs. ,4r-6. Fig. 8 is a similar view showing the form of tension spring employed in connection with the construction shown in Figs. 45. Figs. 9, 10,- and 11 are fragmentary horizontal sections, showing various modifications of my invention applied to different forms of windows.

Similar characters of reference refer to like parts throughout the several views.

Referring to the construction shown in Figs. 1-3, 1 represents the frame of the window which is provided in each of its upright stiles with a vertical channel runway or guideway 2 which may be of usual construction and which has its channel or open side facing toward the adjacent upright edge of the sash. This sash in the present instance comprises a body 3 which may be of any suitable construction and has each of its upright edges terminating Patented Ma S, 19211.

outside of the guideway or runway of the frame. Within the runway is arranged a guide bar 4- which in "eifect forms part of the sash and is capable of sliding vertically in this runway while raising and lowering the sash body for opening and closing the window so as to ventilate in the ordinary way, but the sash body is also capable of swinging vertically on this guide bar for the purpose of reversing the sash body and per mitting either side of its transparent pane to be'more conveniently cleaned from the I inner side of the room. This guide bar is constructed of metal in the form of a channel in cross section and has its channelsides facing the upright edge of the sash body while its convex side faces the back of the runway and is spaced apart therefrom. This guide bar is co-extensive with 'the upper edges of the sash body and its upper end may be connected by means of a cord 5 or similar means with a sash weight or spring such as are commonly employed in connection with sash for the purpose of balancing the weight of the sash.

The pivotal connection between the sash body and the guide bar may be variously constructed but that shown in the drawings is suitable and comprises a metal filling block 6 which is secured within the channel of the guide bar about midway of its length by means of soldering, brazing or.

otherwise and a pivot pin 7 having an inner screw threaded end which engages with: the adjacent upright stile of the sash body and a cylindrical outer end which turns in a horizontal bearing opening 8, formed in the filling block. The web'of the channelbar is provided with an opening 9 through which the pivot pin passes and renders the latter accessible for assembling or dismembering the parts.

In order to produce a weather-tight joint between the sash and the frame for ex-' eluding rain, dust, and dirt, a weather strip is employed which is preferably constructed of sheet spring metal, such as spring brass, .and this in the form shown in Figs. 1-3, comprises two corrugated, fluted or crimped side sections 10, 10 each of which is arv tight joint ranged between one of the lateral sides of the guide bar and the adjacent upright side wall of the runway ofthe frame, and a flat intermediate web 11 connecting the side sections and arranged between the opposing" Sides of the sash body and the guide bar. This weather strip is equal in length to the height of the guide bar and sash body and its opposite ends are flush therewith and its central part is provided with an opening 12 through which the pivot pin 7 passes and causes .the weather strip to move vertically with the sash body and guide bar. The corrngated side sections of this weather strip are constantly under tension and exert a yielding pressure a ainst the guide bar and the runwa there forming a weather between t e guide bar and frameat all times which prevents the passage of any dust, dirt or rain between these members. The weather strip and guide bar are also pressed constantly against the adjacent vertical edge of the sash body by means of one or more tension sprin s 13 preferably of the leaf type, each of w ich is secured at one end to the web of the guide bar and bears at its opposite end loosely against this bar while its intermediate part is bowed and binding as frequently occurs in windows of bears with its convex side against the back of the runway, as clear] shown in Fig.1. As the sash is raised and lowered the tension springs 13 slide u and down on the back of the runway an maintain the guide bar and the weather strip always in proper relation to the sash body, so as to form a weather tight joint between these members.

The -res1 ience, of the weather strip and the tension springs permits them to adapt themselves to an expansion or contraction of the runway us to changes in weather conditions and thereby forms a yieldin joint between the sash and the frame whic prevents the sash from binding in the frame and enables the sash to be moved freely up and down on the frame without liability of ordinary construction.

Furthermore, they ielding mounting of the sash on the win ow frame avoids any looseness between these parts and prevents the same from rattling under wind pressure.

Moreover, this construction is capable of bemg applied to windows now in general use without requiring any extensive alteration or involving any considerable ex nse. The

same is alsolow in cost, capab e of being readily installed and can be operated by persons without any s ial experience.

In the construction shown in Figs. 4, 5, 6 7 and 8 the guide'bar 14 is constructed of wood, and is preferably made of inwardly or rearwardly tapering form in cross section andv seated in a. correspondingly shaped channel 16 on the adjacent central part of the weather strip. In this embodiment of my invention the central section or web portion of the weather strip engages with a longitudinal locking groove 15 formed in the adjacent upright edge of the sash body 40 when the latter is in an upright position, so that upon turning this sash out of its normal position this weather strip and sash bar will be pushed rearwardly toward the back of the runway 17 a distance equal to the depth of the locking groove in thesash body. During this turning movement of the sash on the guide bar the same swings on a pivot pin 18 which passes through the web of this weather strip and has an inner screw threaded end engaging with the sash body and an outer plain end which turns in a bearing opening 19 in the sash bar.

For the purpose of more reliably connecting the weather strip with the wooden sash bar this strip is provided at intervals in its web with spurs or punch marks 20 which enter the wood of the guide bar and retain the same against longitudinal movement relatively to each other. The metal'of the web of this weather strip may also be turned inwardly in the form of a sleeve 21 which surrounds the cylindrical outer part of the in 18 and thereb increases the exconnection. In the instance shown in Figs. 4., 5 and 6 the tension springs 22 are each constructed in the form of a leaf which is secured with its central art to the inner sideof the guide bar and b site ends against the back of the runway.

In the construction shown in Fi 9, the

guide bar 23 engagesdirectly with t e vertical edge of the sash body 41 and is pivotally connected therewith by means of a pivot pin 24 and the weather strip comprises two corrugated or crimped side sections. 25, 25 which are interposed between opposite sides of a rib 26 on the back of this guide bar and the adjacent side walls of the frame runway 27 and an intermediate flat web section 28 connects these side sections and bears a ainst the back or inner sides of said rib. This web is provided midway of its length with an outwardly-turned sleeve 29 which surrounds the inner end of the pivot pin 24 and thereby interlocks the weather strip with the guide bar so as to compel the same to slide together, and also forms a bearing surface for the pivot pin. In'this instance, the tension spring 30 is interposed between the central section or web of the weather strip and the back of the runway.

If desired, my improvements may be modified so as to render the same applicable to windows in which the guiding portion of the sash equivalent to the guide bar is formed inte ally with the body of the sash and slides irectly in the frame runway. Such instances are shown in Figs. 10 and 11 in each of which the sash body 31 is ears at its oppothe respective runway, and a central web section 35 connecting the side sections of this weather strip and interposed between the inner edge'of the rib and the back of the runway. This web is compelled to move vertically with the sash by forming punch marksor spurs 36 in this web which enter the wood of the sash. The side sections of the weather strip shown in Fig. 10 are composed of a plurality of plaits which form six plies, the outmost one of which projects inwardly or toward the back of the runway but in Fig. 11 each of these corrugated side sections 37 of the weather strip comprises only three plies, the outermost.

one of which projects outwardly or fortion permits of mounting windows so that they are weather proof and noiseless and in a manner which is economical and does not detract from the general appearance of the window.

I claim as my invention:

A window comprising a frame havinga channel, a 'sash having an edge .portion arranged in said channel, and a weather strip constructed of spring metal and comprising two corrugated side sections arranged on opposite sides of said edge portion and the adjacent wall of said channel and an intermediate .web section connecting said side sections.
